Brief summary

RATIONALE: Androgens can cause the growth of prostate cancer cells. Drugs, such as ketoconazole, may stop the adrenal glands from making androgens. Lenalidomide may stop the growth of prostate cancer by blocking blood flow to the tumor. Giving ketoconazole and hydrocortisone together with lenalidomide may be an effective treatment for prostate cancer. PURPOSE: This phase II trial is studying how well giving ketoconazole and hydrocortisone together with lenalidomide works in treating patients with prostate cancer that did not respond to hormone therapy.

Detailed description

OBJECTIVES: Primary * Determine the objective response frequency in patients with hormone-refractory progressive prostate cancer treated with ketoconazole, hydrocortisone, and lenalidomide. Secondary * Determine the effect of this regimen on time to clinical progression in these patients. * Determine the safety of this regimen in these patients. * Determine the effects of this regimen on serum cytokines, including tumor necrosis factor-alpha, basic fibroblast growth factor, plasma soluble interleukin (IL)-2 receptor, IL-8, and IL-12, as well as serum vascular endothelial growth factor levels in these patients. * Determine the co-stimulatory effects of this regimen on dendritic cells and CD4-positive, CD25-positive, T-regulatory cells in these patients. OUTLINE: This is a nonrandomized, open-label study. Patients receive oral ketoconazole 3 times daily and oral hydrocortisone twice daily on days 1-28 and oral lenalidomide once daily on days 1-21. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients undergo blood collection periodically during study for evaluation of prostate cancer-specific immune response. Blood samples are assessed by serum analysis, flow cytometry, real-time PCR, and enzyme-linked immunosorbent assay techniques to detect and quantify different cytokines, antiangiogenic markers, dendritic cells, and specific T-regulatory cells. After completion of study therapy, patients are followed at 30 days. PROJECTED ACCRUAL: A total of 34 patients will be accrued for this study.

Inclusion criteria

PATIENTS WITH PROSTATE CANCER PROGRESSIVE AFTER ANDROGEN DEPRIVATION Inclusion Criteria Understand and voluntarily sign an informed consent form. Age 18 years at the time of signing the informed consent form. Histologically confirmed adenocarcinoma of the prostate. Testosterone less than 50 ng/dL. Patients must continue primary androgen deprivation with an LHRH analogue if they have not undergone orchiectomy. All previous cancer therapy, including radiation, and surgery, must have been discontinued at least 4 weeks prior to receive first dose of study drug. Progressive disease after androgen deprivation.

Exclusion criteria

Prior systemic chemotherapy for hormone refractory prostate cancer. Prior neoadjuvant and adjuvant chemotherapy are allowed when completed at least 12 months prior to enrollment. Prior ketoconazole, aminoglutethimide or corticosteroids for the treatment of progressive prostate cancer. Prior immunotherapy including, but not limited to, vaccines, Thalidomide, and or Lenalidomide like agents. Supplements or complementary medicines/botanicals are not permitted while on protocol therapy, except for any combination of the following: conventional multivitamin supplements selenium lycopene soy supplements Patients should review the label with their doctor prior to enrollment, and discontinue disallowed agents prior to study enrollment Serious intercurrent infections or non-malignant medical illnesses including autoimmune disorders that are uncontrolled. Psychiatric illnesses/social situations that would limit compliance with protocol requirements. Evidence of CNS (brain or Leptomeningeal) metastases or large pleural/pericardial effusions. Known contraindication to receive Ketoconazole or Lenalidomide Concurrent use of ketoconazole with statin compounds is absolutely contraindicated. Thus, patients receiving Statin drugs (fluvastatin, atorvastatin, and simvastatin) should discontinue them for at least 7 days before starting ketoconazole. Patients taking astemizole, terfenadine, or cisapride, rifampin or isoniazid are not eligible, unless they agreed to completely discontinue those agents. In that case, any of these agents should be discontinued at least 7 days prior to start therapy with Ketoconazole. Use of any other experimental drug or therapy within 28 days of baseline. Known hypersensitivity to thalidomide or its analogues. Any prior use of Lenalidomide. Known positive for HIV or infectious hepatitis, type A, B or C. Disease free of prior malignancies for 5 years with exception of currently treated basal cell, squamous cell carcinoma of the skin, or carcinoma insitu of the breast.
